Lathe machine operation needs linear torque nd this is done in DC shunt motor i.e constant torque at constant current i.e linear torque. While rolling mills can have diffrent values of torque while considering its operation in certain applications, which can be provided by compound motor i.e b/w series nd shunt.

instead of neutral can we use earth/ground to flow the current in the circuit

We have a 33/11kv switchyard having 12.5 MVA power transformer. We export & import power through this transformer. When we export power, the PF will be depend on GRID PF & when we import power the PF will be depend on our load PF. but the problem is that,when neither we export nor import but our 33KV vCB is in close position,our meter read the power factor 0.14 to 0.25 at that moment. So how can be we improve the power factor at that moment.
